about openvz, for routed configuration with veth (not venet),
https://openvz.org/Virtual_Ethernet_device
gateway of guest is also proxmox host ip
"Using a directly routed IPv4 with virtual Ethernet device"
Situation
Hardware Node (HN/CT0) has 192.168.0.1/24 with router 192.168.0.254.
We also know that IPv4 10.0.0.1/32 is directly routed to 192.168.0.1 (this is
called a fail-over IP).
We want to give this directly routed IPv4 address to a container (CT).
host
----
auto eth0
iface eth0 inet static
address 192.168.0.1
netmask 255.255.255.0
gateway 192.168.0.254
#ip route add 10.0.0.1 dev veth101.0
#echo 1 > /proc/sys/net/ipv4/ip_forward
#echo 1 > /proc/sys/net/ipv4/conf/eth0/forwarding
#echo 1 > /proc/sys/net/ipv4/conf/veth101.0/forwarding
guest
-----

up /sbin/ip route add 192.168.0.1 dev eth0
up /sbin/ip route add default via 192.168.0.1

I'm not expert with openvz (is venet an tap interface ?)
What I don't understand in your setup, is that proxmox host and guest, use the
same external default gateway.
How to you do if guest ip is in different network/range than host ip ???

At least there docu states that it works without any problem:
